In this double reaction we combined potassium acetate with silver nitrate, both of them aqueous solutions. After a few minutes we noted a change as silver acetate, a solid, was formed. This is the formation of a precipitate.
We found that the reactants combined to form a solid which proved true under the subtype: Formation of Precipitate
Subtypes are very helpful in predicting the products of a chemical equation by identifying the reactants and what they may produce together.

This showed that a solid was forming. Before it was just a milky brown liquid. Yet due to our lack of understanding in the stoichiometry area we were confused on the amount of each product was needed for the reaction. When doing this and any experiment it is necessary to know how much of each chemical is needed. Because we did 1 part potassium acetate and 1 part silver nitrate we were actually adhering to the proper ratio in this experiment. For this experiment let it set to see the final amount of silver acetate because it takes about 10 minutes for the amount that we used to finish reacting.
K(C2H3O2) + Ag(NO3) -------> Ag(C2H3O2) + K(NO3)
Potassium Acetate(aq) + Silver Nitrate(aq) ------> Silver Acetate(s) + Potassium Nitrate(aq)
